What classification of matter is liquid mercury?
metallic element
A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
What classification of matter is salt water?
Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound.
What is the classification of pure substance?
Pure substances are further classified as elements and compounds. An element is a substance that consists of only one type or kind of atom. An element is a pure substance as it cannot be broken down or transformed into a new substance even by using some physical or chemical means.
What are classifications of matter?
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

What is distilled water classified as chemistry?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Why is salt water classified as a mixture?
Salt water does not have a uniform composition and we can divide salt and water by simple physical process of evaporation (by boiling the salt water). Thus, salt water is a mixture, with salt as the solute and water as the solvent.
How is matter classified on the basis of chemical composition?
Classification- On the basis of physical properties, matter is classified as solids, liquids and gases. On the basis of chemical properties, matter is classified as elements, compounds and mixtures. Gases- Gases have weak intermolecular flow, high compressibility, and no definite shape and volume.
What are the 4 classes of matter?
There are four natural states of matter: Solids, liquids, gases and plasma.
What makes the atmosphere of Triton so thin?
Triton’s thin atmosphere is composed mainly of nitrogen with small amounts of methane. This atmosphere most likely originates from Triton’s volcanic activity, which is driven by seasonal heating by the Sun. Triton, Io and Venus are the only bodies in the solar system besides Earth that are known to be volcanically active at the present time.
What makes up the core of the planet Triton?
Triton consists of a crust of frozen nitrogen over an icy mantle believed to cover a core of rock and metal. Triton has a density about twice that of water. This is a higher density than that measured for almost any other satellite of an outer planet.
When was Triton discovered in the Solar System?
Global color mosaic of Triton, taken in 1989 by Voyager 2 during its flyby of the Neptune system. Image Credit: NASA/JPL/USGS Triton was discovered on Oct. 10, 1846 by British astronomer William Lassell, just 17 days after Neptune itself was discovered. Triton is the largest of Neptune’s 13 moons.
Which is a higher density Europa or Triton?
Triton has a density about twice that of water. This is a higher density than that measured for almost any other satellite of an outer planet. Europa and Io have higher densities.
